Fair Value models
Bear€11.81Fair Value €15.34Bull€18.87
Price €12.61 · Upside +21.6%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then (€0.5214 per share) are deliberately not added.Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds.Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.
Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card.40/100
Revenue growth is weak: less than 2 % a year.
Revenue growth 1 year
+9.1%
Revenue growth 3 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.
+2.1%
Revenue growth 5 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.

What shareholders gained per year (last 5 years) ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate.

⚠ Revenue per share shrinking 1.4%/yr over ~10Y (margins intact) ⓘStructural-decline marker: revenue PER SHARE has fallen over the last decade (robust median trend, not a single year). Backtested across 2005 to 2017, such businesses trailed the market by about 2.5 percentage points per year. Display only: it does not change the fair value or the quality score.
Growth Forecast
Little optimism in the price
The price assumes less growth than the company has delivered so far and less than analysts expect.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).
−8.2%
The company could shrink this much every year for the next five years and today's price would still be justified.
What forecasts expect ⓘAnalysts publish sales forecasts for the next two fiscal years. For the years after that, growth slows evenly to 2 % a year by year ten (2 % is the long-run rate our models use). Projected years are marked as such.
+4.4%
Yearly sales growth analysts expect, extended to five years.
After inflation (euro area: IMF forecast 2.2% a year to 2030, 2.6% from 2016 to 2025) that is about −10.2% a year for the price and +2.2% for the forecasts.
News mood ⓘNews mood, the average tone of recent news (40 articles), rated against how stocks are usually covered. 🚀 Hype = unusually upbeat · 🙂 Positive = above average · 😐 Neutral = typical · 🙁 Negative = below average · 😨 Very negative = unusually downbeat. It reflects the tone of coverage, not our valuation.Hype
Recent news coverage is unusually upbeat, far more positive than stocks are typically covered.
AI conclusion: Acquisition of A.Hak bolsters BAM's underground energy and water infrastructure via long-term contracts and backlog while advancing the energy transition, yet competitive dynamics and labor constraints continue to limit margins in core construction.
Main risk: Labor constraints and project uncertainties in core construction threaten steady cash flows and margin stability across the combined operations.
BAM's acquisition of A.Hak strengthens its role in underground energy and water infrastructure with long-term utility contracts and a solid order backlog. This shifts more of the business toward the energy transition while the core construction activities still contend with labor constraints and project uncertainties. Our models see the stock as undervalued. Will the added scale in infrastructure deliver steadier cash flows or stretch management attention across the combined operations?
